The NP in 'NP Time' stands for Non-Parental.
Non-Parental Time is time when the children are with neither parent, such as when they are in school or at daycare. Non-Parental Time affects the yearly statistics and is reflected as a percentage for the year.
To use the NP Time field in the Tracker, enter the total number of hours that the child or children were not under the care of either parent for the entire visit.
For example, if there was a 5-day visit and the child was in daycare for 4 hours on 3 of those days then the total time is 12 hours (3 days X 4 hours). You would enter '12:00' in the NP Time field.
Entering NP Time is optional and only necessary when you want to collect statistics on the amount of time the children were not under the direct care of either parent.
